Diana is making smoothie using bananas, cantaloupes, and milk. This table gives the cost, per kilogram, of each ingredient, and the amount, in kilograms, that Diana uses: Ingredient Price per kilogram Amount
Bananas 0.550.550, point, 55 dollars per kilogram xxx kilograms
Cantaloupes yyy dollar per kilogram 1.21.21, point, 2 kilograms
Milk zzz dollars per liter ppp liters
The total cost of the ingredients is 222 dollars.
Write an equation that relates xxx, yyy, zzz, and ppp.

the solution is 2=0.55x+1.2y+zp

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

you,

mrb

(a + b) (a^2 - a b + b^2)
